氢气还原测定铁矿石中硅酸铁的方法,是现有方法中较好的方法。但按目前的使用条件和装置,不适宜大批量分析;另外,硅酸铁的结果是通过全铁量减去氢还原后测得的金属铁(实测Fe~(2+))量之差计算所得,结果误差较大。因此,该方法长期以来未能广泛应用。我们针对该方法上述不足之处,进行了如下改进。 1.还原装置的改进:为提高氢还原测定硅酸铁的分析速度,使之适用于大批量分析的
Hydrogen reduction of iron ore in the determination of iron silicate method is a better method in the existing methods. However, according to current conditions of use and installation, it is not suitable for mass analysis. In addition, the result of iron silicate is calculated by subtracting the difference between the amount of metal iron (measured Fe2 +) measured after hydrogen reduction Income, the results of a larger error. Therefore, this method has not been widely used for a long time. We address the above shortcomings of the method, the following improvements. 1. Reduction device improvements: In order to improve the hydrogen reduction determination of iron silicate analysis speed, making it suitable for high-volume analysis
